I'm testing out a coherent receiver for LF  and looking for something of
air that WILL show an ionospheric effect from time to time.  So looking for
a station transmitting with an Rb or Cs controlled transmission between
200kHz and 500kHz.
My Rx is Low Pass filtered to 500kHz so nothing above that

At the moment, using Radio 4 Droitwich, and MSF 60kHz the trace can be held
on screen absolutely stationary for hours on end,  but those are a bit
boring to look at continuously :-)  So I'd like to have something else to
monitor and demonstrate that will show a slight wander at certain times of
the day.

Is there anything around?  All the NDB signals I've tried are unstable and
their frequency wanders
